41. Gray Red-backed Vole Craseomys rufocanus French: Campagnol de Sundevall / German: Graurételmaus / Spanish: Topillo rojo gris Other common names: Gray-sided Vole Taxonomy. Hypudaeus rufocanus Sundevall, 1846, Lappmark, Sweden. Craseomys rufocanus 1s in the subgenus Craseomys. In the past, it was referred to as Clethrionomys rufocanus or Myodes rufocanus. Majority of genetic variability is allocated in the south-eastern part of the distribution, and distinct phylogenetic lineages occupy the lower Amur region, Hokkaido and adjacent islands, and Sakhalin. Most of the distribution from Fennoscandia to Kamchatka is populated by a single lineage. Five subspecies have been recognized, but a revision is needed. Monotypic. Distribution. Fennoscandia in N Europe E through Siberia to Pacific coast and Kamchatka Peninsula, S as far as Southern Ural, upper reaches of Ob River, N China (Xinjang, Inner Mongolia [= Nei Mongol], Heilongjiang,Jilin, and Liaoning), Mongolia, N Korea, and Pacific Is of Sakhalin, Hokkaido, Kurils, Shantar, and small Is around Hokkaido and in the Sea of Okhotsk. Descriptive notes. Head-body 100-142 mm, tail 27-63 mm; weight 27-52 g. The Gray Red-backed Vole has large ears and eyes and relatively short tail of ¢.40% of head-body length. Females have two pairs of pectoral and two pairs of inguinal mammary glands. Fur is shaggy in summer and long and soft in winter. Coat color is characteristic, with narrow reddish dorsal mantle that is sharply defined against gray sides. Belly is gray, shaded buff and dulled by slate underfur. Tail is sharply bicolored, brownish above and dirty white below. There is considerable seasonal and geographical variation in color. Back of summer pelage is more reddish, and flanks are more buff in the east; island populations on Sakhalin and Hokkaido show less contrast between back and flanks. Juveniles are grayish, with back scarcely tinted red. Skull is massive and angular, with square-like braincase and moderately expanded zygomatic arches. Appearance of molar roots is ...
